Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 80% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES AND TECHNIQUES OF THE FUND
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund’s principal investment strategies are value and international investing. The value oriented philosophy to which the Fund partly subscribes is that of investing in securities believed to be undervalued in the market. The selection criteria are usually calculated to identify stocks of companies with solid financial strength that have attractive valuations (e.g., as measured by low price earnings ratios) and that may have been generally overlooked by the market. The strategy of international investing involves investing substantially all of the Fund’s assets in foreign (non-U.S.) securities (“foreign securities”).


The principal investment technique of the Fund is to employ a “buy and hold” strategy with approximately 50 to 100 high dividend yielding equity securities selected annually from the Morgan Stanley Capital International All Country World Index ex-U.S. Index (“MSCI ACWI ex-U.S. Index”). At least 80% of the Fund’s net assets, plus any borrowings for investment purposes, will be invested in dividend yielding equity securities.


The Fund expects to invest primarily in common stocks, and to a lesser extent, preferred stocks, and may invest in companies of any size. In addition, the Fund is not limited in the amount it may invest in any one country, and its investments may include securities of emerging markets.


The selection criteria used by the Fund’s portfolio managers to identify high dividend yielding equity securities from the MSCI ACWI ex-U.S. Index will generally include dividend yield as well as a combination of factors that relate to profitability and valuation. Certain stocks in the MSCI ACWI ex-U.S. Index may be excluded as a result of liquidity screens applied during the selection process. The number of securities selected each year for inclusion in the Fund’s portfolio will be determined at the discretion of the portfolio managers and will depend on, among other things, the impact that the number of securities held is expected to have on the potential for overall dividend yield in the portfolio, as well as market conditions. While the securities selection process will take place on an annual basis, the portfolio managers may, from time to time, substitute certain securities for those selected for the Fund or reduce the position size of a portfolio security in between the annual rebalancings under certain limited circumstances. These circumstances will generally include where a security held by the Fund no longer meets the dividend yield criteria, when the value of a security becomes a disproportionately large percentage of the Fund’s holdings, or when the size of the Fund’s position in the security has the potential to create market liquidity or other issues in connection with the annual rebalancing or efficient management of the Fund, each at the discretion of the portfolio managers.


The Fund will be evaluated and adjusted at the discretion of the portfolio managers on an annual basis. The next annual consideration of the securities that meet the selection criteria will take place on or about October 1, 2017. Immediately after the Fund buys and sells securities in connection with the Fund’s annual rebalancing, it will hold approximately an equal value of each of the 50 to 100 securities. For example, the Fund would invest about 1/50th of its assets in each of the securities that make up its portfolio if the Fund were to select 50 securities. Thereafter, when an investor purchases shares of the Fund, the Adviser will generally invest additional funds in the pre-selected securities based on each security’s respective percentage of the Fund’s assets at the time.


The Fund employs a strategy to hold securities between its annual rebalancing, even if there are adverse developments concerning a particular security, an industry, the economy or the stock market generally. Due to changes in the market value of the securities held by the Fund, it is likely that the weighting of the stocks in its portfolio will fluctuate throughout the course of the year.


The principal investment strategies and principal investment techniques of the Fund may be changed without shareholder approval. You will receive at least 60 days’ notice of any change to the 80% investment policy set forth above.

Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

There can be no assurance that the Fund’s investment goal will be met or that the net return on an investment in the Fund will exceed what could have been obtained through other investment or savings vehicles. Shares of the Fund are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation. As with any mutual fund, there is no guarantee that the Fund will be able to achieve its investment goals. If the value of the assets of the Fund goes down, you could lose money.


The following is a summary description of the principal risks of investing in the Fund.


Market Volatility and Securities Selection. The Fund invests significantly in equity securities. As with any equity fund, the value of your investment in the Fund may fluctuate in response to stock market movements. In addition, the performance of the Fund may be subject to greater fluctuation when a smaller number of securities are held by the Fund and thus, the Fund’s risk may increase when it holds closer to 50 securities rather than closer to 100 securities. You should be aware that the performance of “value” stocks and “growth” stocks may rise or decline under varying market conditions — for example, “value” stocks may perform well under circumstances in which “growth” stocks in general have fallen. When investing in value stocks which are believed to be undervalued in the market, there is a risk that the market may not recognize a security’s intrinsic value for a long period of time, or that a security judged to be undervalued may actually be appropriately priced. In addition, individual securities selected for the Fund may underperform the market generally.


International Investing. When investing internationally, the value of your investment may be affected by fluctuating currency values, changing local and regional economic, political and social conditions, and greater market volatility. In addition, foreign securities may not be as liquid as domestic securities and are subject to settlement practices and regulatory and financial reporting standards that differ from those in the U.S. Also, while the Fund seeks to invest in a wide range of countries, volatility in a single country or region in which the Fund invests a significant portion of its assets may affect performance. In addition, the markets of emerging market countries are typically more volatile and potentially less liquid than more developed markets. Emerging market countries may have relatively unstable governments and may present the risk of nationalization of businesses, expropriation, confiscatory taxation or, in certain instances, reversion to closed market, centrally planned economies.


Small and Mid Market Capitalization. Stocks of small-cap companies, and to a lesser extent, mid-cap companies, may be more volatile than, and not as readily marketable as, those of larger companies.


Disciplined Strategy. The Fund will not deviate from its strategy (except to the extent necessary to comply with federal tax laws or other applicable laws). If the Fund is committed to a strategy that is unsuccessful, the Fund will not meet its investment goal. Because the Fund generally will not use certain hedging techniques available to other mutual funds to reduce stock market exposure, the Fund may be more susceptible to general market declines than other mutual funds.


Preferred Stock. The value of preferred stock will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of preferred stock. Preferred stock is also subject to credit risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payments. Preferred stock is inherently more risky than the bonds and other debt instruments of the issuer, but typically less risky than its common stock. Preferred stock may be significantly less liquid than many other securities, such as U.S. Government securities, corporate debt and common stock.

[1] Purchases of Class A shares of $1 million or more will be subject to a contingent deferred sales charge ("CDSC") on redemptions made within two years of purchase. The CDSC on Class C shares applies only if shares are redeemed within twelve months of their purchase. See pages 13-15 of the Prospectus for more information about the CDSCs.
[2] Any waivers and/or reimbursements made by SunAmerica pursuant to the Expense Limitation Agreement are subject to recoupment from the Fund within two years after the occurrence of the waiver and/or reimbursement, provided that the Fund is able to effect such payment to SunAmerica and remain in compliance with the expense cap in effect at the time the waivers and/or reimbursements occurred.
[3] Pursuant to an Expense Limitation Agreement, SunAmerica Asset Management, LLC ("SunAmerica" or the "Adviser") is contractually obligated to waive its fees and/or reimburse expenses to the extent that the Total Annual Fund Operating Expenses exceed 1.90%, 2.55%, 1.80% and 1.70% for Class A, Class C, Class I and Class W shares, respectively. For purposes of the Expense Limitation Agreement, "Total Annual Fund Operating Expenses" shall not include extraordinary expenses (i.e., expenses that are unusual in nature and/or infrequent in occurrence, such as litigation), or acquired fund fees and expenses, brokerage commissions and other transactional expenses relating to the purchase and sale of portfolio securities, interest, taxes and governmental fees, and other expenses not incurred in the ordinary course of the Fund's business. This agreement will continue in effect indefinitely, unless terminated by the Board of Trustees, including a majority of the trustees of the Board who are not "interested persons" of the Fund as defined in the Investment Company Act of 1940, as amended.
[4] When the return after taxes on distributions and sale of Fund shares is higher, it is because of realized losses. If realized losses occur upon the sale of Fund shares, the capital loss is recorded as a tax benefit, which increases the return.
